When cooling pure water to a specified temperature (e.g., 2°C), a chiller is typically required. When selecting the equipment, the following factors should be considered:
 
1. Material Compatibility  
   Deionized water has low conductivity and can be corrosive, potentially damaging metal parts over time. Therefore, choose chillers made of corrosion-resistant materials, such as:
    Stainless steel 316L
    PVDF (Polyvinylidene fluoride)
    PE (Polyethylene)
    Avoid copper structures to prevent ion contamination.
 
2. Temperature Control Precision  
   Based on the process requirements, determine whether the chiller needs to:
    Precisely maintain 2°C with high accuracy (±0.1~0.5°C)
    Allow a small fluctuation (e.g., ±1°C) in temperature.
 
3. Equipment Applicability  
   Some laboratory chillers are specifically designed for pure water circulation and feature:
    High-efficiency heat exchange capacity
    Closed-loop systems to prevent external contamination
    Low pollution and low leaching material construction
 
If you require further customization of the cooling system, you should configure it based on factors like the type of pure water, water quality parameters, target temperature, and usage scenarios (e.g., equipment cooling, reactor cooling).
